The jet-setters who flew to London for supermodel Natalia Vodianova‘s Love Ball found themselves out in the cold the other night after a fire alarm went off at The Roundhouse. Kate Moss, Stella McCartney, Diane von Furstenberg and Mario Testino kept warm by passing around bottles of vodkaand watching increasingly curvy Elizabeth Hurley in a see-through sari. The event raised $1 million for Natalia’s Naked Heart Foundation, which has built 23 playgrounds across Russia so far.
